The FT904 Backlash Indicator is used to check the backlash (gear clearance) between the pinion and bevel gear of the differentials for tractor-scrapers. A new measurement and identification mark must be added to the FT904 Backlash Indicator for 637 Scrapers. Illustration 1 shows the correct position for the new mark. Scribe (cut) a straight line across the indicator and add the 637 Scraper identification.
Copies of the drawings needed to make the FT904 Backlash Indicator are available from your Division Service Manager.
